CNC Car Parts: Application of CNC Machining in the Automotive Industry

by Andrew A.

The automotive industry is rapidly growing with new inventions and innovations coming up. Technological changes and modern production techniques have contributed to the continued growth in this sector. When we started with simple vehicles, assembling was mainly done manually. As time went by, new techniques of car assembly came up. We created robots in our assembly plants to aid in manufacturing processes and computer-controlled systems. CNC machining car parts has made production more comfortable, fast, and cost-effective. We can produce multiple high precision car parts at a relatively low cost. Gone are the days when manufacturing processes took long due to a shortage of parts.

CNC machining cart parts and prototypes

Modern-day cars use high precision custom made parts. Most manufacturers prefer hiring custom machining services for mass production of these parts. The following are some CNC car parts:

Engine

A typical car engine comprises of a cylinder block with pistons they move up and down in the cylinders. A metal block drilled, cut and tailored to give a cylinder block through CNC machining. CNC machining has a subtractive nature, making it the best to use for mass production of car engines. The pistons used in internal combustion engines undergo machining to ensure quality and high precision cutting. A CNC machine can produce multiple parts with uniformity with little human labour. The production process can run continuously without breaks, unlike human labour. Computer-aided designs are used in the machining process and can be replicated several times where mass production of the same part is required.

Lighting

Acrylic glass- Poly(methyl methacrylate) (PMMA) is shatterproof and is usually used in headlights and interior car lighting. CNC machining is required to make quality parts. It also allows rapid prototyping of parts for testing and validation.

Interior panels

 Interior car panels like the dashboard and speedometer and such are made of plastic. CNC machining is vital in the production of these parts to ensure that they fit correctly during car assembly.

Drive axels

The components used are driving axels like hypoid gears, and spiral bevel gears are good examples of CNC car parts. These gears have a teeth-like structure which is cut in CNC shops. The geometry complexity of these parts makes CNC machining the best production technique. Since there is no heating of the metals used in CNC machining car parts, structural integrity remains intact. The structural integrity of car parts is essential to ensure durability and safety. Prototypes made through CNC machines pass validation processes faster, speeding up the production process.

Although casting is used to make car parts, some of these parts require CNC machining during finishing. The future of the automotive industry is promising with the integration of new production techniques. Although 3D printing has overtaken CNC machining for the production of parts, machining still contributes immensely in most sectors. The main disadvantage of using CNC machining for automotive components is the production of waste due to the subtractive nature of the technique. With the invention of Autonomous cars, the use of CNC car parts is expected to skyrocket. Rapid tooling is to incorporate production processes to reduce the cost of production and tie required to make CNC car parts.
